This will be the first time I've done one of these and will go on a scale of 1-10 for the whole product and explain my reasoning.
After a quick filing and clipping some of the bigger pieces I rinsed them in soap and water.
The details are very good with no bubbling or warping.
Over all for $8.50 USD for 10 they are easily worth it in my eyes.
I would give them a 8/10.
I decided to do a quick painting tutorial too :D.
After a quick cleaning and washing I started with Vallejo Model Air Grey primer. After laying down a solid coast of that I hit it with VMA sand.
Once that dried, I washed it with watered down Model color black. To shade the cobblestones and add depth.
After that had dried I washed it with some Brown vallejo paint that has the label ripped off. Just use whatever brown or reddish brown you have. Ogryn flesh from GW will work.
This is to add color variation and make it almost like mosaic looking *shrug*.
While I didn't get a picture of it I washed the rubble/sand parts then over brushed it with VMA U.S.A grey then 50/50 with VMA white to highlight it.
Over all they turned out pretty good in my opinion.
Heres a shot of my Jannissary heavy infantry on one of the bases. I'll take better pictures of the model itself in my light box later.
(Not pictured I painted the rim with VMA black, I know its super important but I couldn't get the lighting right to show how important it is).
